実験手順
3,5-Dimethyl-4-pyrimidin-2-ylpiperazine-1-carboxylic acid tert-butyl ester (294 mg) was dissolved in ethanol (2 ml), 4N hydrochloric acid (ethyl acetate solution, 2 ml) was added and the mixture was stirred at room temperature for 4 hr. The solvent was evaporated, and ethyl acetate (3 ml) was added to the obtained residue. The solid insoluble in ethyl acetate was collected by filtration and dried to give the title compound (281 mg).
